Can I add a bend in my vent stack?

[hellocward]

Hello, I want to add a bend to my vent stack before it goes through the roof. Is this ok to do? The vent serves one shower drain and one toilet drain. See photo. Green is what it does currently. NOTE: I'd like to REMOVE the GREEN LINE entirely, and replace with the yellow line. Will this still work with a bend in the main stack?

Thanks

Yep

Yep

Thanks. Also, just to be clear, I'd like to REMOVE THE GREEN LINE entirely, and replace it with the yellow one. Can this work with a bend only?

I can’t see what’s in the floor from your pic.

It connects vertically to a horizontal drain 6" below the sun floor

Will this work?

Yes as long as the pipe is 42 inches about the flood level rim of the fixture .

Ok thanks, is that because 42" is to code? The bend is about 80" above subfloor so looks good. Thx.

Yes code say a vent must be vertical and not bend until above the flood level rim by 6 inches which is usually 42 inches from the floor .

You’re moving the vents connection to the drainage system.

I can’t see that plumbing in the pic you posted, but it’s probably ok.

So the pic you posted isn’t enough info to make a judgement. What you’re doing above the floor is fine, it’s below the floor that I can’t see.
